That's a heck of a length given that it looks like you're proposing 300mm tube (based on the 400mm base). How deep are you going to go with the foundations?

Thanks Chris,

As Andrew pointed out I would probably need a 1m cubed foundation, and I like your idea about the gussets running the whole length, at least for the bottom section.

Cheers
